While PR [#218](https://github.com/PyAr/PyZombis/pull/228) solved the issue #211 by adding a python example, the english page for the lecture remains unchaged. It must also be updated with the relevant example. The Spanish lecture at: lectures/TWP40/TWP40_12_en.html, also has a typo which should be fixed. <img width="1423" alt="Screenshot 2024-03-13 at 4 58 32 AM" src="https://github.com/PyAr/PyZombis/assets/89126072/3bac6ae8-6fa8-4bc5-87c1-8fff25806b54">
